Node.js is a JavaScript runtime environment that is built on the V8 engine of Chrome. Being event-driven and featuring non-blocking I/O benefits, Node.js is lightweight, as well as fast.

Because of the many perks that Node.js offers, it has been able to impress a lot of industries such as Healthcare, e-commerce, IT and more. The simplicity it offers makes Node.js irresistible. Plus, it’s open-source and offers cross-platform development as well.

Unlike unresponsive and slow applications that can negatively impact business operations, Node.js brings its robust, flexible and strong personality to offer wonderful results.

Let us find out some of the advantages of Node.js and why it is so preferred choice among developers.

  • Ensures High Performance

Node.js based web applications are great at multitasking. The runtime environment has single-threaded, event-driven architecture. Still, it can process multiple requests at once without any hassle.

That too, without putting too much pressure on the RAM. In addition, the non-blocking I/O operations enable faster application execution.

  • Offers Cross-Platform Development

Being packed with full-stack development features, Node.js makes it simpler to address issues in the development phase instantly.

With cross-functional abilities, one can create teams that work in tandem to resolve problems as they come during the development phase.

This way, it becomes easier to reduce production times.

  • Faster Response Times

Offering a single-threaded event-loop architecture, Node.js enables a non-blocking asynchronous model. That said, more threads can be created without the need for employing greater resources.

Thus boosting applications responsiveness while multiple users work simultaneously on the application.


Apart from the good part, there are a few limitations that Node.js accompany too.

  • Heavy Computation Reduces Performance

Although considered fairly fast, the issue occurs when there is a CPU bound task request. During the heavy request made to the event loop, Node.js allot the entire CPU availability to this process.

Only when it’s completed, the CPU becomes free to process other requests. This ends up slowing the application processing. Therefore, Node.js is not suitable for too heavy computation.

  • The problem of Call-back Hell

Because of the Node.js asynchronous characteristic, the runtime environment depends a lot on call-backs.

These are the functions executed when the task finishes in the queue. Therefore, the environment maintains an array of queued tasks in its background. And each containing its call-back.

This sometimes results in call-back hell. This makes it difficult to maintain code with Node.js.

  • Frequent Changes in API

Node.js suffers from frequent API changes. These APIs being backwards-incompatible forces developers to edit the access code in order to sync these code with the latest Node.js API versions.
